Why 4 Stroke Outboards Gained Popularity?
Today, the popularity of 4 stroke outboards has increased. People like to use these engines as they are more economical and efficient compared to other types of outboard motors. Until the late 1990’s 2 stroke outboards or 2 stroke engines were used in small boats.
But as 4 stroke engines revolutionized the moto industry, people started fiddling with the idea of using 4 strokes on outboards but there were challenges as well.
The first thing was the cost of producing 4 strokers. The production cost of a 4 stroke engine is higher than 2 strokes.
These engines require high-quality metals and components to produce stronger and more durable parts that can withstand high temperatures and pressures. As outboards were meant for water crafting corrosion resistance is required. So, using such high-quality components gave the 4 strokers a new and expensive look than their counterpart 2 strokes outboards. Slowly all these problems were overcome by giving 4 stroke outboards new innovative designs. Now, people are using several 4 strokers on outboards because of their durability and fuel efficiency.
Pollution and noise were a major disadvantage for 2 stroke outboards. 2 stroke outboards have a higher capacity of generating toxic emissions and noise pollution.
The next disadvantage was the cost of producing fuel as the engine requires fuel with oil mixed in it. Due to this reason, people prefer efficient engines so they can save on fuel costs as well as maintain a healthy environment. This led to the popularity of 4 strokes outboards.
How Does a 4 Stroke Outboard Work?
A 4 stroke outboard consists of four main parts. The first part is the inside of the engine which contains the piston, crankshaft, connecting rod, camshaft, etc.
The second part is the outside of the engine containing the oil pump, fuel pump, alternator, valves, and carburetors.
The third part is the clutch mechanism that transfers power from the engine to the propeller. This system contains a low-speed shaft, high-speed shaft, and gearbox with clutches.
The final part of a 4 stroke outboard is rigging which takes power from the engine to control functions in separate compartments in the boat. Like controlling lights, bilge pump, throttle, etc.
The basic working of a 4 stroke outboard is the same as a 2 stroke engine. Fuel is burned with air and the resultant reaction makes a piston move up and down inside the cylinder. This movement rotates a crankshaft which in turn powers the propeller or watercraft through a driveshaft running from the engine.
The difference is that in a 4 stroke outboard one piston comes up and down twice as opposed to two pistons working in tandem in a 2 stroke engine. This gives it the advantage of getting high RPMs and high power output along with more torque than the other engines. So, this alluring feature gave rise to the popularity of 4 stroke outboards.
How Reliable Are 4 Stroke Outboards?
